Best Practices for Sustainably Integrating School Gardens into the Corvallis SchoolDistrict Wellness Policies

Creator:: Radloff, Cassidy N.
Abstract:: Participation in school garden programs improves health outcomes in K-12 student and is an effective tool for experiential learning. Although most schools in the Corvallis School District have a school garden, none are currently integrated into the curriculum. Using a cross-sectional,online survey, I learned that the majority of parents of...

Use of extractable lipofuscin as an age biomarker to determine age structure of ghost shrimp (Neotrypaea californiensis) populations in west coast estuaries

Creator:: Cassidy, Katelyn M.
Abstract:: Determining age in crustaceans is inherently imprecise because they molt periodically and do not retain hard structures throughout their lifespan. Morphological measurements, such as carapace length, are often used to estimate age because methods for direct ageing do not exist. However, variability in individual growth rate and molt frequency can...

Advancing forced draft biomass cookstove technology with computational fluid dynamics modeling

Creator:: Cassidy, Liam J
Abstract:: Today, billions of people are limited to using biomass-fueled traditional fires as a primary energy source for cooking and purification of drinking water. Reliance on open burning of biomass leads to exposure to high levels of household air pollution which has been estimated to claim over 1.5 million lives annually,...

Comparing vegetation and soils of remnant and restored prairie wetlands in the northern Willamette Valley

Creator:: Taylor, Sara M.
Abstract:: Native prairies of the Willamette Valley are considered among the rarest of Oregon's ecosystems (Clark and Wilson, 2001). As a result of agriculture conversion, urban development and cessation of native burning, Willamette Valley prairies have become highly fragmented and invaded by non-native species, leaving little room for native plant diversity....

The legacy of Dr. Francis Hole : examining soil organic carbon after 50 years of detrital manipulation

Creator:: Townsend, Kimberly L.
Abstract:: Models of ecosystem carbon (C) balance generally assume a strong relationship between net primary productivity (NPP), litter inputs, and soil C accumulation, but there is little direct evidence for such a coupled relationship. Using a unique 50-year detrital manipulation experiment in a in a mixed deciduous forest and restored prairie...

Visualization of N-ary Relationships

Creator:: Qu, Botong
Abstract:: N-ary relationships, which relate N entities where N is not necessarily two, are omnipresent in real life. In this thesis, we develop a visualization technique for N-ary relationships. First, we propose a visual metaphor that utilizes vertices and polygons to represent entities and N-ary relationships. Based on this visual metaphor,...

Depression risk : an examination of rural low income mothers

Creator:: Guyer, Amy M.
Abstract:: This study used a multi-method approach to explore factors associated with high and low depression in a sample of rural mothers living in poverty. From a sample of 117 women with very high or very low CES-D depression scores, 40 cases were randomly selected for in-depth qualitative analysis. Qualitative comments...

Informal social support and attrition among nonpartnered, rurally-located, poor mothers

Creator:: Amity, Frederica A.
Abstract:: This qualitative study used interview transcripts to find clues to attrition from a longitudinal study among nonpartnered, rurally-located, poor mothers, a generally vulnerable population with characteristics commonly associated with attrition (low-income, low levels of educational attainment, and rural location). Drawing on Rural Families Speak data, the author used the number...

Ecology of the northern subpopulation of northern anchovy (Engraulis mordax) in the California Current large marine ecosystem

Creator:: Litz, Marisa N. C.
Abstract:: Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...
